Anemone fish (also called “clownfish”) are well-known from their appearances in the Pixar movies “Finding Nemo” and “Finding Dory”.
They have a symbiotic relationship with certain species of sea anemone, where they live with the anemone and do not get stung by its tentacles.
In turn, the anemone fish defends the anemone from predators. Research has shown that these anemone fish are sensitive to changes in ocean chemistry and will wander further away from home as waters become more acidic due to the ocean’s absorption of carbon dioxide.
And now, a new study shows that these anemone fish may not have the genes necessary to adapt to changes in the marine environment.
